Pull requests are welcome. I had wanted to line break this module for better viewing, but I'm currently having trouble figuring out how to get some of the code to work over multiple lines. I'll keep working at it and hopefully I'll have a more web-friendly version soon.
To understand what attributes each structure has, see the Add-Type section at the top of the script. Skip to content. Star 1. Branches Tags. To import a particular version of the module, the end-user can use the MinimumVersion or RequiredVersion parameters of the Import-Module cmdlet. For example, if the Fabrikam module is available in versions 8. The installer adds both of the module paths to the PSModulePath environment variable value.
When these steps are complete, the ListAvailable parameter of the Get-Module cmdlet gets both of the Fabrikam modules. If both modules are imported into the same session, and the modules contain cmdlets with the same names, the cmdlets that are imported last are effective in the session.
Command name conflicts can occur when the commands that a module exports have the same name as commands in the user's session. When a session contains two commands that have the same name, Windows PowerShell runs the command type that takes precedence. When a session contains two commands that have the same name and the same type, Windows PowerShell runs the command that was added to the session most recently. To run a command that is not run by default, users can qualify the command name with the module name.
To run the cmdlet, preface the command with the module name, such as:. To prevent name conflicts, module authors can use the DefaultCommandPrefix key in the module manifest to specify a noun prefix for all commands exported from the module. Users can use the Prefix parameter of the Import-Module cmdlet to use an alternate prefix.
The value of the Prefix parameter takes precedence over the value of the DefaultCommandPrefix key. The [System. Path] class has static members that can be used to make your code work on any platform:.

Important Once you have added the path to PSModulePath , you should broadcast an environment message about the change. Parameter Reservation. The value for this paramater must be the DHCPReservation object of the reservation you wish to remove. Removes a scope from a server.
This example removes the Sets the number of confliction detection attempts made by the DHCP server. This example sets the conflict detection attempts on dhcp Parameter Number.
The number of conflict detection attempts to make. Setting value to 5. This example defines the DNS update configuration for the reservation The resulting configuration would be:. Dynamic Updates: Enabled.
Update Trigger: Client Request. Legacy Client Updates: Enabled. The resulting effect is that the scope will henceforth inherit its DNS update configuration from its parent server. Legacy Client Updates: Disabled. Update Trigger: Always. Parameter DNSConfiguration. It is used if you have a defined DNS update configuration that you want to apply to a new object. Parameter Value. The value for this parameter is an integer. This is used if you want to input the raw option value for DNS update configuration.
You can create a valid value using the following logic:. Start at 0. A value of 0 means DNS update configuration is completely disabled. If you want the Update Trigger to be "Always", add If you want to discard old DNS records, add 4. If you want to allow dynamic updates, add 1. Note: A value of -1 is only applicable within the context of this module and is used to denote no defined configuration, which means that the given object inherits its DNS update configuration from its parent.
If the given object is the DHCP server, then it uses the default configuration, which is equal to a value of 5. Parameter AllowDynamicUpdate. The value for this parameter is true or false. If declared, the value is true and enables dynamic updates, otherwise dynamic updates is disabled. Parameter UpdateTrigger. The value for this parameter is a string value of 'Always' or 'ClientRequest'. If not declared the value defaults to 'ClientRequest'. If declared, the value is true and enables the discarding of stale DNS records A and PTR when a lease is no longer active, otherwise it is disabled.
Parameter AllowLegacyClientUpdate. If declared, the value is true and enables the updating of DNS records belonging to legacy pre Windows clients, otherwise it is disabled. Parameter RestoreDefaults. The value for this parameter is true of false. This parameter supercedes all other configuration parameters.
This example enables the Deny filter and any MAC addresses defined therein, but does nothing to the Allow filter. This example disables both the Allow and Deny filters.
Parameter AllowList. This parameter defines the state of the Allow filter. Disabled - Does not filter MAC addresses to see if they are allowed. Parameter DenyList. This parameter defines the state of the Deny filter. Disabled - Does not filter MAC addresses to see if they are denied. Set the value of an option from a given server, scope, or reservation. This example sets the value for option on the If this value is defined as an object, that updated object will be returned upon success.
The integer value of the option whose value you wish to set. This switch parameter is only needed if you want to add IPs to OptionID 6 that are not currently online. This parameter is only valid for Windows servers and higher. Sets the description of a DHCP scope.
This example sets the description for the Sets the lease time for clients on a DHCP scope. This example sets the lease time for the Parameter Seconds. Time in seconds for the duration fo the lease. Sets the name of a DHCP scope. This example sets the name for the
